He knew that he wasn't going to be welcome in this house, and he was perfectly fine with that. So all ready he knew other arrangements needed to be made, but at least for tonight, they were allowed to stay because he was getting his footing in this world. Gold didn't exactly have much trouble adjusting as he'd made the adjustment once before going from Fairytale Land to Storybrooke. But here, there was magic, which he would have to account for. Would he revert back into the Dark One? Would it remain held at bay because the magic here might be different? Or was it going to manifest itself in different ways? He didn't quite have the answer to that, so he was just going to have to wait and see how this place affected him.
Sitting down on the bed, he leaned his cane against the bed, ensuring that it didn't fall over or clatter out of reach should he need it again. Looking at Belle, he of course inwardly hated that she brought up not killing Regina. That was much like asking him to give up his magic altogether. Regina deserved to die for the things she had done, not least of all taking Belle away from him. But Gold was a patient man, he could work something out to get around it. He always did have a plan. Looking Belle in the eye, he nodded a bit.
"I promise, Belle. I won't kill her. We only just found each other again, I don't want to lose you." Which was the truth of the matter. He didn't want to lose Belle again, and he was fairly certain he could somehow find a way to hurt Regina or have something happen to her that didn't involve him killing her. But that was for a later time. Right now, he was focused on Belle and he squeezed her hand within his, giving her a smile. "I am so very glad to see you again. In the time that you've been here without me, how have you been? Did you find it difficult?" No doubt she had found it difficult to some extent given she'd been locked up in Storybrooke for 28 years, so this world was undoubtedly a strange and frightening experience for her.
